OWINGS MILLS, Md. — The Ravens began preparations for their Week 15 contest against Philadelphia without their top cornerback on the practice field.

Jimmy Smith was not present for Baltimore’s Wednesday walk-through as he recovers from a right ankle sprain suffered in Monday’s loss to New England. The 2011 first-round pick left the game late in the first quarter and did not return, but head coach John Harbaugh has offered no clarity on his status for Sunday’s game or beyond.

“I really don’t want to get into that, to be honest with you,” Harbaugh said. “I don’t really see any purpose to get into that. Thanks for asking.”

Should Smith not be able to play against the Eagles on Sunday, the Ravens would likely turn to Shareece Wright to start opposite rookie Tavon Young. Slot cornerback Jerraud Powers practiced on a limited basis despite leaving Monday’s game with a concussion.

Reserve defensive back Anthony Levine (toe) and linebacker Terrell Suggs were absent from Wednesday’s practice. Suggs received a veteran day off.

Tight end Crockett Gillmore (hamstring) made his return to practice on a limited basis after missing his sixth straight game. Rookie guard Alex Lewis (ankle) was a full participant after practicing on a limited basis last week. He appears poised to return against Philadelphia after missing four consecutive games.

Third-year wide receiver Michael Campanaro was officially promoted to the 53-man roster on Wednesday and is expected to be in the return specialist mix with veteran safety Lardarius Webb, according to Harbaugh. The Ravens waived four-time Pro Bowl returner Devin Hester on Tuesday.

“That was a little bit of a tough move just because we have so much respect for Devin and the effort he’s put in,” Harbaugh said. “I told him I feel like we didn’t get the job done. We didn’t do enough to make the return game productive enough to make it worthwhile.”

The Eagles were without top receiver Jordan Matthews (ankle) and veteran running back Darren Sproles (concussion) during their Wednesday practice.

The Ravens will wear their black jerseys for their home finale on Sunday. They own a 15-6 all-time record when wearing their alternate tops and are 12-3 under Harbaugh.
